Sharp valuation acceleration ($3.6B in 2021 to $10.1B in March 2026), driven by continued wearables/health-data momentum and a marquee athlete/celebrity investor roster (Cristiano Ronaldo, LeBron James, Rory McIlroy, and others) that also functions as a distribution asset. The Series G-2 tranche is a SAFE-to-preferred conversion (confirmed via a SuRo Capital Corp. SEC filing), not a separately-led round. CEO Will Ahmed said at the March 2026 Series G close that it is expected to be WHOOP's 'last private round of financing' with an IPO as the 'next step'; a later (Aug 2026) Bloomberg interview reportedly has him targeting roughly 18 months out, tied to a Boston HQ expansion and 600-person hiring plan. No S-1 or confidential filing exists yet, unlike wearables peers Oura and Strava, which filed confidentially in 2026.

| Notes | CEO Will Ahmed: Series G is expected to be WHOOP's 'last private round of financing... our next step is an IPO.' Grouped by trade press with Oura and Strava as part of a 2026 wearables IPO wave, though WHOOP is the only one of the three without a filing. |
